Description

Technical Field

[0001] The utility model relates to the technical field of milling mechanisms, in particular to a milling mechanism for machining a waist drum-shaped elongated spindle. Background Art

[0002] As the power of gas turbines increases, the waist-drum-shaped slender spindle, as its core component, needs to have higher precision and more stable performance. This requires further research and optimization of processing technology to meet market and technical needs. At present, there are still many scientific research gaps and limitations in the processing technology of the waist-drum-shaped slender spindle of megawatt-class gas turbines.

[0003] The waist drum-shaped slender spindle is processed by a milling mechanism. In order to ensure the processing accuracy of the waist drum-shaped slender spindle, the tool needs to have sufficient cutting capacity. Therefore, when the cutting edge is severely worn and cannot meet the processing requirements, the milling cutter needs to be replaced.

[0004] However, the current milling cutter replacement process is too cumbersome, time-consuming and laborious. It not only requires bolts to be fixed, but also requires a hammer to knock the milling cutter into position. Moreover, the stability of the milling cutter after replacement is not very good. Therefore, there is an urgent need for a milling cutter that can be quickly positioned and replaced and is firmly installed. Utility Model Content

[0008] In addition, a preferred structure is that a connecting cavity is transversely penetrated through the output shaft, and the connecting cavity is connected with the positioning cavity.

[0009] In addition, a preferred structure is that the first mounting member and the second mounting member can be adapted to be spliced ​​together to form a "ring", and the splicing points of the first mounting member and the second mounting member are both set as slopes.

[0010] In addition, a preferred structure is that limiting columns are fixedly and vertically arranged in the middle of the inner sides of the first mounting member and the second mounting member, and when the first mounting member and the second mounting member are in contact, the ends of the limiting columns on both sides are in contact with each other.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-6 The invention discloses a milling mechanism for processing a waist-drum-shaped slender spindle, comprising a milling mechanism body 1, an output shaft 2 is rotatably mounted on the milling mechanism body 1, a milling cutter 3 is mounted at the bottom of the output shaft 2, and a first mounting member 4 and a second mounting member 5 are mounted on both sides of the output shaft 2. A positioning member 31 is vertically arranged on the top of the milling cutter 3, a limited position cavity 32 is horizontally penetrated in the positioning member 31, a positioning cavity 21 is arranged at the end of the output shaft 2, and the positioning cavity 21 is adapted to the positioning member 31. The output shaft 2 is driven to rotate by the milling mechanism body 1, and the milling cutter 3 can be driven to rotate by the output shaft 2, so that the waist-drum-shaped slender spindle can be processed by the milling cutter 3. It is worth noting that the specific structures and working methods of the milling mechanism body 1, the output shaft 2 and the milling cutter 3 are all existing technologies currently disclosed on the market, which are common knowledge known to those skilled in the art, and do not belong to the main technical problems to be solved in the present technical solution, so they are not elaborated in the present utility model.

[0023] A communication cavity 22 is transversely formed on the output shaft 2 , and the communication cavity 22 is communicated with the positioning cavity 21 .

[0024] The first mounting member 4 and the second mounting member 5 can be adapted to be spliced ​​to form a "ring", and the splicing parts of the first mounting member 4 and the second mounting member 5 are both set as slopes. Through holes 41 are vertically penetrated on both sides of the first mounting member 4, and threaded holes 51 are opened on both sides of the second mounting member 5 below the through holes 41, and screws 7 are inserted into the corresponding threaded holes 51 on the first mounting member 4 and the second mounting member 5. By setting the screws 7, the first mounting member 4 and the second mounting member 5 can be assembled to ensure their stability after installation.

[0025] The first mounting member 4 and the second mounting member 5 are both fixedly and vertically provided with a limiting column 6 in the middle of the inner side, and when the first mounting member 4 and the second mounting member 5 are in contact, the ends of the limiting columns 6 on both sides are in contact with each other. By providing the limiting columns 6 on the first mounting member 4 and the second mounting member 5, the positioning member 31 can be fixed, thereby achieving fixed installation of the milling cutter 3.

[0026] When the first mounting member 4 and the second mounting member 5 are assembled, the limiting columns 6 on both sides are respectively inserted into the limiting cavity 32 from both ends of the connecting cavity 22 .

[0027] In this embodiment, when the user needs to install the milling cutter 3, it is only necessary to insert the positioning member 31 above the milling cutter 3 into the positioning cavity 21 in the output shaft 2. (It is worth noting that in the process of inserting the milling cutter 3, the connecting cavity 22 and the limiting cavity 32 need to be in the same direction.) After the milling cutter 3 is inserted, the connecting cavity 22 is aligned with the limiting cavity 32 and is connected to each other. At this time, the user can install the first mounting member 4 and the second mounting member 5 on the outside of the output shaft 2, and the limiting columns 6 on the first mounting member 4 and the second mounting member 5 are inserted into the limiting cavity 32 through the connecting cavity 22, and then the ends of the limiting columns 6 on both sides are located in the limiting cavity 32 and contact. In this way, the positioning member 31 can be fixed and clamped by the limiting column 32, so that the installation of the milling cutter 3 can be achieved.

[0028] Furthermore, after the limiting column 6 is inserted into the limiting cavity 32, the user only needs to insert the screws 7 through the through holes 41 into the threaded holes 51, thereby realizing the splicing of the first mounting member 4 and the second mounting member 5, thereby preventing the limiting column 6 from falling off or loosening due to the first mounting member 4 and the second mounting member 5.

[0029] In the utility model, by setting the milling mechanism body 1 and the milling cutter 3, the milling processing of the waist drum-shaped slender spindle can be realized, and by the coordinated setting of the first mounting member 4 and the second mounting member 5, the positioning member 31 can be fixedly clamped in the positioning cavity 21, thereby realizing the installation of the milling cutter 3. This fixing method is fast and convenient, and the installation is stable, which is convenient for users to use.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
